The value of $$\frac{\sin 30^\circ \sin 60^\circ}{\cos 60^\circ \cos 30^\circ } - \tan 45^\circ$$ is:
$$\frac{\sin 30^\circ \sin 60^\circ}{\cos 60^\circ \cos 30^\circ } - \tan 45^\circ$$
Put the values in the expression,
$$\frac{\frac{1}{2} \times \frac{\sqrt3}{2}}{\frac{1}{2} \times \frac{\sqrt3}{2} } - 1$$
= 1 - 1 = 0
